t=22

We see that a negative is being added to t. There is no negative or coefficient in front of the variable, however, so this problem is fairly easy to do in our head the traditional way. We see that we are adding -3, so we cancel this out by subtracting -3 on both sides (which is the same as adding 3). We recall that 19 plus 3 is 22, so t=22.
